Outline
• Introduction– Catholic Health Initiatives- St. Elizabeth– Why antimicrobial stewardship?
• Objectives– Cost savings– Improved antibiotic use
• Methodology– Clinical Decision Support
• Results– Cost savings– Clinical pathway optimization– Success stories
• Discussion• Conclusion
Introduction
• Catholic Health Initiatives – 105 hospitals– 4 academic medical centers– 19 states– 30 critical access hospitals
• St. Elizabeth– 260 bed community hospital– Medical, Pharmacy, and Nursing
students from University of Nebraska and Creighton University
Antimicrobial Stewardship
• Centers for Disease Control and Prevention (CDC):– 3/2014; Published Core Elements of Hospital
Antibiotic Stewardship Programs(ASPs)• Leadership Commitment
• Accountability
• Drug Expertise
• Action
• Tracking
• Reporting
• Education
• President Obama:– 9/2014; Presidential Order mandating Task
Force and 5-Year Plan for combating antibiotic resistance
Antimicrobial Stewardship• Centers for Medicare and Medicaid Services(CMS):
– 12/2014; Updated checklist for infection control in hospitals
1.c.9 The hospital has written policies and procedures whose purpose is to improve antibiotic use (stewardship).
1.c.10 The hospital has designated a leader (e.g., physician, pharmacist, etc.)responsible for antibiotic stewardship outcomes.
1.c.11 Policy and procedures require practitioners to document an indication, dose, and duration for all antibiotics.
1.c.12 The hospital has a formal procedure for all practitioners to review antibiotics prescribed after 48 hours (e.g., antibiotic time out).
1.c.13 The hospital monitors antibiotic use (consumption) at the unit and/orhospital level.
Background
• Pre - ASP Operations – Decentralized pharmacists cover Critical Care, Progressive
Care, Medical, Oncology, and Burn Units– Pharmacokinetic Services by Pharmacy for select antibiotics– Infection Control Committee– Infectious Disease Physicians not employees of the hospital
– contract with provider group– Verigene
• Rapid detection of G+ and G- blood stream infections• Pharmacy occasionally called first; dependent on
microbiologist discretion– Yearly antibiogram
Pharmacist-Led Antimicrobial
Stewardship Program
• Recruit Committee – monthly meetings– ID Physician, 2 Internal Medicine Physicians, Infection
Control, Microbiology, Chief Medical Officer
– Pharmacy Clinical Coordinator attended meetings to assist in the handoff after the pharmacist completed residency
• Identify Goals– Cost reduction, clinical pathway optimization, success stories
• Process Implementation– Clinical Decision Support
– Quality and quantity metric development
– Provider education
Pharmacist-Led Antimicrobial
Stewardship Program
What is Clinical Decision Support(CDS)?
“CDS systems link health observations with health knowledge to influence health choices by clinicians.” - Robert Hayward, Center for Health Excellence
Software that applies rules (e.g. if-then statements) to patient data.-Computerized alerts and reminders for providers-Clinical guidelines-Condition-specific order sets-Patient data reports and summaries-Documentation templates (interventions, etc.)
TheradocTM
ASP Pharmacist using Theradoc
Intervention period
• Pharmacy resident spent 1 to 3 hours/day for three months using a Clinical Decision Support (CDS) System report tailored to Antimicrobial Stewardship
– Process accelerated as pharmacist and hospital physicians grew familiar with process
• Pharmacy resident made interventions to providers based on daily report via face to face conversation or phone/pager
• The report was broken up by unit following the intervention period for clinical pharmacists to use
• Interventions during the 3 month period will be compared to baseline
ASP Pharmacist using Theradoc
Intervention period
Criteria that prompted alert:
-Antibiotic level, new
-Relevant culture: blood, respiratory
-Therapeutic Antibiotic Monitoring;
-drug-bug mismatch
-inadequate/no coverage
-overlapping therapy
-broad spec. de-escalation
-no positive cultures (72 hrs)
-redundant therapy
-IV to PO switch – anti-infectives
TIME INTENSIVE STEP
Pharmacist-Led Antimicrobial
Stewardship Program
Example: Two separate providers providing overlapping empiric therapy
• Pharmacist documents all interventions • Cost savings assigned by Catholic Health Initiatives• Cost savings comparison of pharmacist interventions before and after ASP

Goals
-Cost savings-Clinical pathway optimization
-Success stories
Cost savings (soft) from improved antibiotic use before ASP Pharmacist: $23,336/month
Cost savings (soft) from improved antibiotic use with ASP Pharmacist: $40,110/month
Worth noting; -Self reported-Costs are based on best available literature-Length of stay and ABX $$/Patient Day data is pending
Results-Cost savings
-Clinical pathway optimization-Success stories

Presented at December Meeting;Baseline data (3 month average) from PremierTM
Per Johns Hopkins Antibiotic Guide*:
• Empiric Inpatient Treatment for Acute Uncomplicated Cystitis– “Fluoroquinolones are no longer considered first line treatment and should be
reserved for special situations such as allergy or intolerance to other agents”
• Empiric Inpatient Treatment for Acute Uncomplicated Pyelonephritis– “Use local antibiotic susceptibility data to guide initial empiric therapy”
Ciprofloxacin 400 mg IV q12h (if local fluoroquinolone resistance rates < 10%)
Levofloxacin 500 mg IV once daily (if local fluoroquinolone resistance rates <10%)
• Complicated– “Fluoroquinolones (FQ) are reasonable empiric choices if patient has not
received an FQ in recent past, is not from a long-term care facility, and FQ resistance is low.”

• From LTC -> admitted to critical care unit(CCU)
• Medical Resident empirically selected Piperacillin-Tazobactam, Vancomycin, and Levofloxacin
• ESBL Klebsiella
– Microbiology left message with nurse at 0430
• Alerted via Theradoc – seen in morning review @ 0800
– Needed carbapenam – contacted attending MD
• Pt. switched by 0830
Clinical Decision Support (cont’d)
Other functionalities of Clinical Decision Support that an ASP Pharmacist could use
• Patient flags
• Antibiogram
• Estimated doses for antibiotics• Frequency * number of days• 741 doses of levofloxacin during December vs. 624 during
February (~5 minutes to run this report)
Obstacles• Non-residency/infectious disease trained pharmacist using unfamiliar
software to make infectious disease interventions
– Providers not always receptive
• Initial Theradoc reports took entire day to sift through
– No expert on site
• Data not readily available (usage, etc.)
• Wide variation on what antimicrobial stewardship looks like across and within academic and non-academic medical centers
– Differing metrics, process, medication use systems

Using Clinical Decision Support
Conclusions
• A pharmacist can lead an antimicrobial stewardship program at a 260-bed community hospital
• Clinical Decision Support(CDS) can identify intervention opportunities for pharmacists with little/no specialty training
• Minimal daily activity on CDS alerts is financially lucrative and benefits patients and institutions
Pharmacist-led Antimicrobial Stewardship
Using Clinical Decision Support
Future• Skin/soft tissue order set
• CAP/HCAP order set
• Provider eduction
• Reporting– ABX $/1000 patient days
– Length of stay for sepsis, pneumonia
– Monthly reports of antibiotic usage for sepsis, pneumonia, and UTI
• FTE Request submitted using stewardship and intervention data– Approved by position control and facility
